As a note, I have driven a car at its top speed once. I had a mid 90s Geo Metro with the I3 engine in a 70MPH zone and it had a top speed of about 72 on level ground.
I've probably run every vehicle I've ever owned until it topped out (or as close as practical). And I've owned some fast ones. I still think it's a mostly useless metric. Even in Nevada with 20 miles of visibility and empty road in front of you, there's a limit to what you can do on a public road without the odds rapidly stacking against you with each added mph. And the vast majority of tracks don't have a straight long enough to get to 260mph. So lot of damned good that 2.9MM car does you on I-405 at 5:00...or on a track day.
0-60, OTOH...
Looking at the most accident-prone cars, all the ones I recognize are sports cars: https://www.cars.com/articles/whats-the-most-crash-prone-car...
Ever driven a Metro at 70mph? I'll take the Bugatti at 200mph, thanks.
any car with a top speed of 261 mph (420 kph) seems inordinately likely to end up in an air-conditioned garage and never driven at all.
(That's typically what happens to many of these 'hyper-cars' - they are treated as long term investments rather than vehicles, heaven forbid you affect the future resale value by actually driving it...).
Often luxury car companies will refuse to build any more because each additional car built reduces the value of all existing cars.
So the answer is 0. This marketing doesn't need to sell any cars to justify the cost.
Also, I think this is about Lego, not Bugatti (but I’m not excluding the possibility that it’s mutually beneficial).
“On [the Chiron] project, we get back in the black,” Bugatti’s Head of Production Christophe Piochon told me. The development of the Veyron’s complex systems over its lifetime, which laid the solid engineering foundation for the Chiron, resulted in $1.62 billion in investment costs. “By the end of the Chiron’s run, we’ll be profitable,” Piochon promised.
The Veyron somewhat infamously was a net loss for Volkswagen, despite its massive price. But ultimately its role was to be a halo car for the entire Volkswagen Group, and as such profit on the car itself wasn't such a concern.
